Coolant System Bleeding Procedure Questions

ZeroDfx · Feb 26, 2020

I have reviewed the bleed procedure (turn car on but don't start it, heater temp dials full open, fan off, hold accelerator pedal down 10+ seconds). Pump is supposed to run for 12 minutes.

Will I see any indicator light on the dash to tell me process has started?
Will I hear the pump engage and turn on?
Do I need to sit in the car for the full 12 minutes and not open the door to disrupt the power?
Will I get any indicator light on the dash to tell me the process is completed?
How do I know if I succeeded in activating and completing he bleed process?

Thanks for your feedback.

If you have a V8 this does not apply. Those instructions apply to cars with electric water pumps. I'm sure there is a procedure for the V8, I don't know what it is. newtis.info is a service manual.

There should be two water pumps on the V8 and one of them aids in coolant bleeding procedure.

Cooling system is vented while it is filled and during subsequent idle operation.
Note:
Before filling, turn on ignition. Set blower to low level. Seat heating controller to maximum temperature. This ensures that the heater valves are fully opened and the auxiliary water pump starts up.
Important: The auxiliary water pump must deliver coolant in order to ensure fully venting!

Thank you gentlemen for clarifying the distinction between the 6 and 8 cylinder!
I'll pull the cap and let her idle with heater full open and see if I need to add coolant.
Thanks again!
